Abstract

L'invention concerne des sorbants qui améliorent l'adsorption de substances perfluoroalkyle et polyfluoroalkyle (PFAS). Les sorbants présentent des microstructures qui adsorbent efficacement les PFAS, comme montré par la combinaison d'un indice volumétrique d'iode élevé et d'un nombre volumétrique de mélasse élevé. L'invention concerne également des procédés de fabrication et des procédés d'utilisation.
